The comments and bidding assume a weak NoTrump and a 4 card major Acol style. Notwithstanding the consequent inference of rebids by opener as to his hand strength being differnt, therefore, from Standard American, reading the panelists' comments is interesting. I found this a low-level set of problems compared to ACBL's bulletins and of course considerably lower than Bridge World's difficult problems. What was especially worrying (or amusing) was the number of first round rebid problems on which experts could not seem to agree on the other side of the Atlantic, and I had thought that we Americans were a confused lot in bridge bidding theory. Reese and Wolff and Kantar are among some quoted panelists (I am well aware that the last two are American superstar player and theorist/coach respectively).
